Washougal Town Square Raingarden Courtyard and Stormwater

Located at the City Center, this mixed use office/retail project was envisioned to be a catalyst for town center redevelopment. GreenWorks designed the site improvements to reinforce pedestrian and visual connections to the urban fabric and to the Columbia River Gorge area as a demonstration project. GreenWorks implemented goals for a sustainable development model by creatively designing stormwater solutions, rainwater harvesting, a central courtyard, and native plantings in an urban context for the one block development. GreenWorks used 3-D modeling to enable the design team, developer and local staff to visualize design solutions. This project is one of the 10 LEED-ND pilot projects by the USGBC for the nation.

Headwaters at Tryon Creek

GreenWorks provided landscape architecture services in master planning a new 2.8 acre mixed residential development near the headwaters of Tryon Creek. The project includes a variety of residential types including elderly housing, town homes, and a Portland Development Commission (PDC) built low-income apartment building. All of the new residential developments, along with an existing apartment building, were designed to be integrated with the daylighting of a tributary of Tryon Creek. The development was coordinated with many local agencies (PDC, Portland Department of Transportation, Portland Parks and Recreation Bureau, and Bureau of Environmental Services) to extend the daylighting project from the headwaters of the tributary in a park adjacent to the site, through the site and adjacent neighborhood to Tryon Creek. The goal of the developer and the design team was to incorporate the buildings, parking, plazas, bridges, and other site elements into a cohesive sustainable site development that takes full advantage of this daylighting opportunity. GreenWorks services include schematic design, design development, construction documentation, and services during construction. This project is certified LEED Silver.

BES Columbia Slough Stormwater Retrofit Inventory

In January 2010, GreenWorks and BES staff conducted intensive field work locating and documenting potential locations for stormwater facilities throughout the Columbia Slough Watershed in North Portland. The Columbia Slough has been designated a high priority area by the City of Portland for improving watershed health and reducing pollutants. The project team focused on four target areas where green street facilities would maximize stormwater quality treatment and capture contaminated sediment before being discharged into the Slough. Each potential green street facility was ranked based on its potential performance, feasibility, and cost. GreenWorks assisted BES in project prioritization and provided an overall ranking using Geographic Information Systems (GIS). Over 150 potential green street facilities were identified, which would potentially result in stormwater treatment from over 35 acres of impermeable surfaces.

Albany Stormwater Standards

GreenWorks has worked over the past several years with City of Albany staff to develop stormwater quality standards for development to meet DEQ regulatory requirements.  The products include new and  updated sections of City Administrative Codes, Development Codes, Engineering Standards, Standard Construction Specifiations, and Standard Drawings.   The draft products are currently in the public review process, with adoption and implementation tentatively planned by the end of 2014.  Draft documents are all available for review on the City of Albany/Public Works/Engineering web page.
